CONSTRUCTION OF PAPER CONTAINERS.

Specification of Letters Patent.

Patented May d, M5915,

Application filed December 9, 1913. serial No. 805,481.

To all whom it may concern Be it known that I, ADOLPH F. RIETZEL, a citizen of the United States, and a resident of Westerly, in the county of Washington and State of Rhode Island, have invented. certain new and useful Improvements in Construction of Paper Containers, of which the following is a specification.

My present invention relates to the construction of paper containers and particularly to the manner of and means for securing the heads to the body of such forms of containers as comprise a cylindrical body portion constructed of terial.

The object of the invention is to cheapen the construction of containers of the above type and at the same time to provide a secure and cheap fastening for holding the heads effectively in place.

A further ob ect is, as far as is possible in containers-constructed mainly of. paper or similar material, to simulate thecoopering operation of wooden containers; that is to complete the assembling of the container by merely employing hand tools.

To these ends the invention consists in the improved construction of paper container and in the novel parts and details of construction hereinafter more particularly described and then specified in the claims.

In the accompanying drawings, Figure 1 is a vertical central section .through a paper container constructed in accordance with this invention. Fi 2 is an enlarged section through one side 0 the upper end thereof.

I am aware that-inpaper containers, that is where the body is f rmed of paper or similar material, that it has'been proposed to secure the heads to the body by continuous longitudinal metallic strips or Wires each of .which strips'engage and hold both heads. This cconstruction has been de'emed essential to the production of a practical paper container-in which great weight could be shipped but is open to the objection that containers so constructed are a costly assembling proposition-as well as necessitating the employment of considerable weight of metal; By the construction herein pro posed by me such continuous strips are dispensed with and the assembling can be done by hand similar to the operation of cooperin a wooden ke or barrel.

hmbody of 516 container consists of a paper or similar mav closely around the cylinder 1 straight-walled cylinder of paper or other similar material 1 formed in any desired manner The cylinder 1' is preferably formed of a number of layers of paper superimposed on-each other, preferably by windlngor splnning, and compressed into a very solid mass, the various layers being united by a suitable adhesive whereby a very rigid wall of any desired thiclm'ess'is attained; "lhe specific manner of forming the cylindrical body portionformsno'part of my invention and further description will be dispensed with. v

2 indicates metal bands or hoops passin at each en The bands 2' are each provided with a lat eral inwardly projecting flange 2 which seats onthe end of the cylinder 1 and protects the edge -ot the paper layers from mutilation.

The disk'B is provided with an annular metal rim to which it may be secured in any desired manner. lhe rim in its simplest form. 1s a double-flanged or Z-shaped' form hav ng an outwardly projectingflange 4 seatlng on the flange 2 of the hoop 2 and an inwardly projecting flange 5 against which the disk 3 seats, said flanges being preferably disposed in difi'erent planes. The flanges'i and 5 are joined by a vertical ring 15 which when the rim is inserted in. the cylinder bears against the inner-wall thereof thus firmly holding the edge ofvthe cylinder between it and the band 2 and preventing any disintegration thereof. The disks 3 may, if desired, be fastened to theflange 5 by rivets or staples 6 or-otherwise. o

7 indicates a strip of metal, preferably flat, forming a fastener for the head and of -which there may 'be any desired number spaced around the periphery of the cylinder 1. The strips or fasteners for one head are separate from and independent of those for the other head and are disposed longitudinally of the cylinder near the ends. One of the ends of the strip is fastened to the cylinder 1 at a point some distance from the end of the cylinder by a rivet or staple 8 passing laterally through the wall of the cylinder and clenched on either the inside or outside thereof. Preferably, to strengthen the fastening, a. pair of plates or washers 9, 10 are placed on opposite surfaces of the cylinder and secured thereto by a rivet or staple 11, the strip fastening staple 8 passing through said washers whereby the latter forms a bearing for the same and protects the paper.

The free ends of the fasteners 7 are bent over the head rims as at 12 and secure the heads to the body in an obvious manner. If desired the free end of the fastener may be bent laterally into a flange 13 adapted to seat against the outer surface of the head.

It will be understood that the invention is not limited to the particular style of fasener shown nor to the specific type of device for securing it to the body but that modifications and equivalents may be resorted to Without departing from the spirit of the invention as set forth in the appended claims.

What I claim as my invention is 1. In a device of the character described in combination, a cylindrical body portion, a hoop of l..-shaped cross section protecting one end of said body portion, a plurality of plates arranged in pairs with one plate of each pair on the interior and the other plate on the exterior of said body portion, rivets passing through said plates and said body portion and securing said plates in position at a substantial distance from the end of said body portion, metallic strips secured at one end by certain of said rivets, a head constructed to fit within said body portion, an annular rim of Z-shaped cross section constructed torest on the end of said body portion and covering a part of said hoop, and hooks on the ends of said metallic strips to retain the head in position within the end of said body portion.

2. In a device of the character described in combination, a cylindrical body portion,

a pair [of adjacent metallic members arranged with one of said members on the interior and the other of said members on the exterior of said body portion, rivets passing through said metallic members and through the body portion to secure said metallic members in position, a head-constructed to fit within the end of said body portion, an annular metallic ring of substantially Z- shaped cross section, having one ledge secured to the head and the other ledge con-
